PROCESS OF COATING WALLS AND OTHER SURFACES.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed November 5, 1915. Serial No. 59,799.

To allwhom it may concern:

Be it known that I, HARRY F. CLAYTON, a subject of the King of Great Britain, residing in the city of Toronto, in the county of 6 York, Province of Ontario, Canada, have invented a certain new and useful Improved Process of Coating walls and other Surfaces,

of which the following is a specification.

This invention relates particularly to the 10 treatment of walls or other stationary sur faces, which cannot be treated in furnaces,

for the production thereon of a smooth lossy surface similar ,to that of enameled iron ware.

In carrying out my process I apply to the surface to be coated a finely ground fusible enamel or metallic powder ,mixed in water or other convenient li uid'medium. For my purpose an easily fusi ble glass colored wit 20 metallic oxids is well suited.' One or more coats ma be applied, if necessary, to give a suflicient y thic coating. The surface, when dry, is then subjected to the action of radiant heat at a very high temperature applied for without the e ects of the heat extending below the surface. Such radiant heat at a sufiiciently high temperature can be obtained by heating a plate of refractory material by means of an oxy-acetylene blow pipe or electrically, and by moving this plate as slowly as may be necessary over the coated surface and at a distance determined by the tem erature of the plate,'the coating may be used.

In the case of plaster, stucco, brick or tile walls and'the like, the enamel coating may be applied direct to the surface with the certainty that it will adhere when fused. In the case of wood or other non-mineral sur- 40 faces a mineral filling coat carried in a liquid medium capable of readily penetrating the pores of the wood ma be thoroughly worked into the surface be ore the enamel coat is applied. China clay mixed with oil 46. or glucose is suitable for this pu use If a metallic coating be desired metallic powders suspended in any suitable medium. such for e coating example as the so called banana oil, may

be substituted for the enamel, and ma be used either a plied directly to the sur aces or over a filing coat such as hereinbefore referredrto.

A heater suited for my purpose is illustrated in the accompanying drawings in which- Figure 1 is a longitudinal section of a suitable heating device; and Fig. 2 a front view of the same.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

1 represents a suitable casing lined with refractory material. The front of this casmg is formed by a plate 2 of some suitable re r'actory material which is a good radiator of heat. Gra hite or carbon such as used for the manu acture of arc-light pencils is well suited for my purpose. This late is located close to the front edge of t e case and may be made adjustable to and from the edge if necessary; Behind this plate is located an oxy-acetylene blow pipe 3 rovided with a number of 'ets directed against the back of the plate. his will effectively heat the plate. Electrical or other means of heating might, of course, be substituted. The back of the casin is provided with a handle 4 by means of w ich it may be moved as desired when in use.

What I claim as my invention is:

A process of coating surfaces in 81311. which consists in forming thereon a. coating of a finely divided fusible mineral and thereafter fusing said coating by the action of radiant
